Freesound - Feedback-001_Glitchy by AlienXXX

Recent discussions with another Freesounder made me go back to sound design using feedback loops in Ableton Live.

Note: THESE SOUNDS ARE OFTEN LOUD AND HARSH. PLAY AT LOW VOLUME!

This pack contains glitchy sounds which seem to have come from some circuit bend or some mad DIY device.

Sounds have been created using one of my tried and tested recipes: use a pitch recognizing synth (or sound generator/effect), feed it some frequency rich audio.
This output is the recorded output, but it is also fed into a feedback loop. Usually this feedback loop works best at generating crazy sounds if it contains a pitch shifting effect. - preferably one that does not just add harmonics or subharmonics. So a frequency shifter will work better than an octaver.
Other kinds of effects that create non-harmonic contents will also work well - another good choice is a sample rate reducer.

Whenb a feedback loop like the ones described is used is used, glitchy sounds and little beep sequences can be created, even if the input sound is a simple sine wave.

In this pack, I have used:
- Live's Operator synth for the initial sound input.
- Several Live's own effects (to control the feedback loop, compressor, limiter, EQ, Utility)
- The feedback loop contains Live's Simple Delay and Frequency Shifter
- The pitch recognizing sound generator is the free mda Tracker, which can be found here:

If you plan to try something like this
- make sure you put a limiter on the output. So your ears and your speakers don't blow up in case of runaway feedback (it will happen!)
- If you have a midi controller it is a great idea to assign a knob or fader to the volume on the feedback loop (so it is easy to control things). If you do not have a midi controler, in Live you can still assign a key on your computer keyboard to mute the feedback loop channel.
